This paper investigates the role of habits in the consumption function. Two types of habits are considered: rational and myopic, these being distinctions which have long been made in the literature on systems of demand equations. In both cases past consumption affects current preferences, thus...

Aggregate stock prices, relative to virtually any indicator of fundamental value, soared to unprecedented levels in the 1990s. Even today, after the market declines since 2000, they remain well above historical norms. Why? We consider one particular explanation: a fall in macroeconomic risk, or...

Abel (2002) shows that pessimism and doubt in the subjective distribution of the growth rate of consumption reduce the risk-free rate puzzle and the equity premium puzzle. We quantify the amount of pessimism and doubt in survey data on US consumption and income. Individual forecasters are, in...

This Paper introduces state dependent utility into the standard Mehra and Prescott (1985) economy by allowing the representative agent’s coefficient of relative risk aversion to vary with the underlying economy’s growth rate. Existence of equilibrium is proved and its asymptotic properties...

We use prices of equity index options to quantify the impact of extreme events on asset returns. We define extreme events as departures from normality of the log of the pricing kernel and summarize their impact with high-order cumulants: skewness, kurtosis, and so on. We show that high-order...

We develop a DSGE model in which monetary policy generates endogenous movements in risk. The key feature of our model is that households rebalance their financial portfolio allocations infrequently, as they face a fixed cost of transferring cash across accounts. We show that the model can...

This paper examines the relationship between the equity premium and the risk free rate at three different maturities using post-1973 data for a panel of seven OECD countries. We show the existence of subsample instabilities, of some cross country differences and of inconsistencies with the...

Among the most important pieces of empirical evidence against the standard representative-agent, consumption-based asset pricing paradigm are the formidable unconditional Euler equation errors the model produces for a broad stock market index return and short-term interest rate. Unconditional...
